Casio G-Shock unleashes its latest heavyweight diving watch with the introduction of the GDF-100BB-1JF “Solid Black.” The timepiece arrives in a print-less face as debossing serves to delineate the “G-SHOCK” and “SHOCK RESISTANT” moniker as well as the other function branding. Aside from the customary G-Shock functions of shock resistance, water proofing, calendars, alarms and time zone support, the GDF-100BB-1JF boasts a solitary all-black-everything aesthetic, white backlighting and blue indigo. Rakuten now has stock for a retail of ¥13,524 JPY (approximately $170 USD).
